Question: "How can you believe in salvation by faith alone when the only occurrence of ‘faith alone’ in the Bible (James 2:24) says that salvation is not by faith alone?"
Answer: It is entirely true that the one verse in the Bible that contains the exact phrase “faith alone” seems to argue against salvation by faith alone. James 2:24 reads, “You see that a person is justified by works and not by faith alone” (ESV). However, rejecting the doctrine of salvation by faith alone based on this verse has two major problems. First, the context of James 2:24 is not arguing against the doctrine of salvation by faith alone. Second, the Bible does not need to contain the precise phrase “faith alone” in order to clearly teach salvation by faith alone.
James 2:14-26, as a whole, and especially verse 24, causes a lot of confusion. The passage definitely seems to cause serious problems for the “salvation by faith alone” concept. First, we need to clear up a misconception, namely, that James means the same thing by “justified” in James 2:24 that Paul means in Romans 3:28. Paul is using the word justified to mean “declared righteous by God.” Paul is speaking of God’s legal declaration of us as righteous as Christ’s righteousness is applied to our account. James is using the word justified to mean “being demonstrated and proven.”
The 2011 NIV provides an excellent rendering of James 2:24: “You see that a person is considered righteous by what they do and not by faith alone” (emphasis added). Similarly, the NLT translation of James 2:24 reads, “So you see, we are shown to be right with God by what we do, not by faith alone” (emphasis added). The entire James 2:14-26 passage is about proving the genuineness of your faith by what you do. A genuine salvation experience by faith in Jesus Christ will inevitably result in good works (Ephesians 2:10). The works are the demonstration and proof of faith (James 2:18). A faith without works is useless (James 2:20) and dead (James 2:17); in other words, it is not true faith at all. Salvation is by faith alone, but that faith will never be alone.
While James 2:24 is the only verse which contains the precise phrase “faith alone,” there are many other verses that do, in fact, teach salvation by faith alone. Any verse that ascribes salvation to faith/belief, with no other requirement mentioned, is a declaration that salvation is by faith alone. John 3:16 declares that salvation is given to “whoever believes in Him.” Acts 16:31 proclaims, “Believe in the Lord Jesus, and you will be saved.” Ephesians 2:8 says, “For by grace you have been saved through faith.” See also Romans 3:28; 4:5; 5:1; Galatians 2:16; 3:24; Ephesians 1:13; and Philippians 3:9. Many other scriptures could be referenced in addition to these.
In summary, James 2:24 does not argue against salvation by faith alone. Rather, it argues against a salvation that is alone, a salvation devoid of good works and obedience to God’s Word. James’s point is that we demonstrate our faith by what we do (James 2:18). Regardless of the absence of the precise phrase “faith alone,” the New Testament definitely teaches that salvation is the product of God’s grace in response to our faith. “Where, then, is boasting? It is excluded. On what principle? . . . On that of faith” (Romans 3:27). There is no other requirement.
